Tokyo: The United States had warned Japan not to purchase the Senkaku Islands last year, former U.S. Assistant Secretary for East Asian and Pacific Affairs Kurt Campbell said in an interview.
Japan had consulted with the State Department prior to the purchase and was given `very strong advice not to go in this direction,` Campbell revealed.
The U.S. stressed that purchasing the islands could `trigger a crisis` with China, which too claims the islands, Japan Times reports.
Campbell said that even though the US warned Japan, it decided to go in a different direction.
The central government purchased three of the five islands from their private owner in September to bring them under its control.
The action enraged the government in Beijing and sparked a wave of anti-Japanese protests across China.
Campbell, while reiterating that the United States takes no position on the disputed territory, stressed that Washington wants to see "effective, positive diplomacy" between China and Japan, the report added.
